IMPROVEMENT IN STEAM-GENERATORS.

Specication forming part of Letters Patent N0. 50,109. dated September26, 1865.

To all whom 'it may concern Be it known that I, EDWARD FARON, of thecity of New York, N. Y., have invented certain new and usefulImprovements in Steam-Boilers; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the drawings which accompany this specilication and form a partthereof, and to the letters of reference which are marked thereon.

The -nature of my invention consists in the construction of a boilerwith a series of inclined tubes or fines placed immediately over thefire, through which the water passes, in connection with the steam whichis generated in them, and in further providing a second series of tribesor ues above the first, through which all the steam passes into thesteam-box, and in which tubes or iiues the steam in its passage issuper-heated, both series of tubes or ues being entirely within theinclosure of the furnace.

To enable those skilled in the art to make and use my said improvement,I will proceed to describe the same.

In the drawings, Figure l is a longitudinal section, and Fig. 2 is afront view.

A is the furnace, containing both series of tubes or flues within it.

B B are the steam-generatin g tubes or flues, forming the iirst seriesof tubes or iiues above the gratebars, and endingvat the water-line.

O C are the superheating-tubes, fbrming the second series, which areentirely above the water-line, and through which all the steam must passon its way to the steam-box D.

E E are the water-spaces, and F is the connection to the smoke-pipe.

G G are man-holes to the water-spaces, and H the manhole to thesteam-box.

J J are perforated plugs inserted in the receiving-ends of thesuperheating-tubes C C, reducing the size of the aperture for thepurpose of insuring an even flow of steam through all the tubes, andthereby producing and delivering into the steam-box D steam of uniformquality. The steamboX D has no connection with any other part of theboiler, and

therefore all the steam generated must pass through thesuperheating-tubes C C before entering the steam-box on its way to thecylinder.

L is a water-guard, to prevent the Water from entering thesuperheating-tubes, and K is a perforated plate, to prevent any flamewhich might pass the generating-tubes from reaching thesuperheatingtubes, and is located between the generatingtubes and thesuperheatingtubes, and rests upon stops upon the ends of the furnace.

It will be seen that the advantage of r'ny improvement over other formsof boilers is found in the saving of weight and space, also in thefacility with which it can be cleaned and repaired, and in thoroughlysuperheating the steam, by which a saving of fuel is effected.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The construction ot' a steam -boiler in which all the steam generatedshall pass through the superheating-tubes, as and for the purpose setforth.

2. The construction of a steam-boiler in which the generating andsuperheating tubes are arranged horizontally, or nearly so, and entirelywithin the furnace, substantially as described.

3. The perforated plugs J J on the receivin g-ends ofthesuperheatingtubes,for the purpose of equalizing the tlow of steam in allthe superheating-tubes alike.

4. The perforated plate K, in combination with the generating-tubes andthe superheating-tubes, as and for the purposes set forth.

5. The water-guard L, in combination with the superheating-tubes, in themanner and for the purpose described.

6. The arrangement of the generating-tubes B B and thesuperheating-tubes O O in such a manner as that the fire passes aroundthe outside of both, as set forth and described.

EDWARD FARON.
